No-hair and almost-no-hair results for static axisymmetric black holes and ultracompact objects in astrophysical environments Classical Quant. Grav. (IF 3.6) Pub Date : 2025-03-30
Carlos Barceló, Raúl Carballo-Rubio, Luis J Garay and Gerardo García-MorenoNo-hair theorems are uniqueness results constraining the form of the metric of black holes in general relativity. These theorems are typically formulated under idealized assumptions, involving a mixture of local (regularity of the horizon) and global aspects (everywhere vacuum spacetime and asymptotic flatness). This limits their applicability to astrophysical scenarios of interest such as binary black

Francesco Capozzi, Bhaskar Dutta, Gajendra Gurung, Wooyoung Jang, Ian M. Shoemaker, Adrian Thompson, Jaehoon YuNew gauge bosons coupled to heavy neutral leptons (HNLs) are simple and well-motivated extensions of the Standard Model. In searches for HNLs in proton fixed-target experiments, we find that a large population of gauge bosons (Z′) produced by proton bremsstrahlung may decay to HNLs, leading to a significant improvement in existing bounds on the (mHNL,Uα), where Uα represent the mixing between HNL and

Marc Kamionkowski, Anubhav MathurEarly dark energy solutions to the Hubble tension introduce an additional scalar field which is frozen at early times but becomes dynamical around matter-radiation equality. In order to alleviate the tension, the scalar’s share of the total energy density must rapidly shrink from ∼10% at the onset of matter domination to ≪1% by recombination. This typically requires a steep potential that is imposed

No manifest T duality at order α′3 Phys. Rev. D (IF 4.6) Pub Date : 2025-03-31
Steven Weilong Hsia, Ahmed Rakin Kamal, Linus WulffWhen reduced from 10 to 10−d dimensions tree-level string theory exhibits an O(d,d) symmetry. This symmetry, which is closely related to T duality, appears only after certain field redefinitions. We find a simple form for a subset of these redefinitions at order α′3 and show that they cannot be lifted to ten dimensions. This is inconsistent with “manifestly T duality invariant” approaches such as generalized

Md Riajul Haque, Debaprasad Maity, Rajesh MondalWe have discussed in detail how neutrinos produced from inflaton solely through gravitational interaction can successfully reheat the Universe. For this, we have introduced the well-known type-I seesaw neutrino model. Depending on seesaw model parameters, two distinct reheating histories have been realized and dubbed as (i) Neutrino dominating: Following the inflaton domination, the universe becomes

Selection rules for RG flows of minimal models Phys. Rev. D (IF 4.6) Pub Date : 2025-03-28
Valentin Benedetti, Horacio Casini, Javier M. MagánMinimal d=2 conformal field theories (CFTs) are usually classified through modular invariant partition functions. There is a finer classification of “noncomplete” models when S duality is not imposed. We approach this classification by starting with the local chiral algebra and adding primaries sequentially. At each step, we only impose locality (T duality) and closure of the operator algebra. For

Signal-preserving CMB component separation with machine learning Phys. Rev. D (IF 4.6) Pub Date : 2025-03-28
Fiona McCarthy, J. Colin Hill, William R. Coulton, David W. HoggAnalysis of microwave sky signals, such as the cosmic microwave background, often requires component separation using multifrequency methods, whereby different signals are isolated according to their different frequency behaviors. Many so-called blind methods, such as the internal linear combination (ILC), make minimal assumptions about the spatial distribution of the signal or contaminants, and only

Quantum computing for energy correlators Phys. Rev. D (IF 4.6) Pub Date : 2025-03-28
Kyle Lee, Francesco Turro, Xiaojun YaoIn recent years, energy correlators have emerged as powerful observables for probing the fragmentation dynamics of high-energy collisions. We introduce the first numerical strategy for calculating energy correlators using the Hamiltonian lattice approach, providing access to the intriguing nonperturbative dynamics of these observables. Furthermore, motivated by rapid advances in quantum computing hardware
